All of these ideas are very familiar, and already existing, within the audience of the movie.

Yet, Mr. Moore amplifies and steers these beliefs toward his own unique conclusions.

So for the greatest reward: Instead of the more complex process of trying to alter pre-existing beliefs by presenting false evidence, try steering people's already existing beliefs toward your own agenda.

That way, when people one day "suddenly" arrive to think the same way you do, it'll feel so natural to them it's as if they thought of it themselves.
